LABOPORT Pumps and Systems
Use
2.
Use
2.1. Proper Use
The pump/system is exclusively intended for transferring gases
and vapors.
Owner's responsibility
Operating parameters and
conditions
Only install and operate the pump/system under the operating
parameters and conditions described in chapter 5, Technical data.
Make sure that the installation location is dry and the pump/system
is protected against rain, splash, hose and drip water.
Requirements for
transferred medium
Before using a medium, check the compatibility of the materials of
the pump head, diaphragm and valves with the medium.
Before using a medium, check whether the medium can be
transferred danger-free in the specific application case.
Only transfer gases which remain stable under the pressures and
temperatures occurring in the pump.
High performance condenser
The high performance condenser must be installed on the outlet
side of the pump; if it is installed on the inlet side there is a danger
of implosion.
Observe the correct usage of the gas- and cooling liquidconnections on the high performance condenser. Inlet and outlet
connections for the gas are not interchangeable.
Accessories
Laboratory equipment or additional components connected to a
pump/system have to be suitable for use with the pneumatic
capabilities of the pump (see chapter 5.1, page 10).
2.2. Improper Use
The pump/system may not be operated in an explosive atmosphere.
The pump/system is not suitable for transferring dusts.
The pump/system is not suitable for transferring liquids.
For LABOPORT systems with vacuum controller: The vacuum
system must not be used if the entry of air or gas into the vacuum
system during venting (pump vent valve) could result in the
creation of reactive, explosive or otherwise hazardous mixtures
(e.g. with the medium).
The pump/the system must not be used to create vacuum and
overpressure simultaneously.
An overpressure must not be applied to the suction side of the
pump/ the system.

Safety
LABOPORT Pumps and Systems
3.
Safety
Note the safety precautions in chapters 7. Installation,
mounting and connection, and 8. Operation.
The pump/system is built according to the generally recognized
rules of technology and in accordance with the occupational safety
and accident prevention regulations. Nevertheless, dangers can
result during their use which leads to injuries to the user or others,
or to damage to the pump/system or other property.
Only use the pump/system when it is in a good technical and
proper working order, in accordance with its intended use,
observing the safety advice within the operating instructions, at all
times.
Personnel
Make sure that only trained and instructed personnel or specially
trained personnel work on the pump/system. This especially
applies to assembly, connection and servicing work.
Make sure that the personnel has read and understood the
operating instructions, and in particular the "Safety" chapter.
Working in a safetyconscious manner
Observe the accident prevention and safety regulations when
performing any work on the pump/system and during operation.
Do not expose any part of your body to the vacuum.
Open housing parts with notice sticker (see fig. 1) only after
separating mains plug from power source.
Fig. 1: Notice sticker
Handling dangerous media
When transferring dangerous media, observe the safety
regulations when handling these media.
Handling flammable media
Be aware that the pump/system is not designed to be explosion-proof.
Make sure the temperature of the medium is always sufficiently
below the ignition temperature of the medium, to avoid ignition or
explosion. This also applies for unusual operational situations.
Note that the temperature of the medium increases when the pump
compresses the medium.
Hence, make sure the temperature of the medium is sufficiently
below the ignition temperature of the medium, even when it is
compressed to the maximum permissible operating pressure of the
pump. The maximum permissible operating pressure of the pump
is stated in the technical specifications (see chapter 5.1, page 10).
If necessary, consider any external sources of energy, such as
radiation, that may add heat to the medium.
In case of doubt, consult the KNF customer service.
Environmental protection
6
Store all replacement parts in a protected manner and dispose of
them properly in accordance with the applicable environmental
protection regulations. Observe the respective national and international regulations. This especially applies to parts contaminated
with toxic substances.
LABOPORT Pumps and Systems

Diaphragm pumps transfer, compress (depending on pump version) and evacuate gases and vapors.
The elastic diaphragm (4) is moved up and down by the eccentric
(5) and the connecting rod (6). In the downward stroke it aspirates
the gas to be transferred via the inlet valve (2). In the upward
stroke, the diaphragm presses the medium out of the pump head
via the outlet valve (1). The transfer chamber (3) is hermetically
separated from the pump housing (7) by the diaphragm.

continuously and works against its vacuum. If there is a vacuum
controller, it will switch the pump off once the selected target
vacuum has been reached.
With two vacuum controllers it becomes possible to simultaneously
run two different and independent processes with just one pump.
Once one vacuum controller’s set point has been reached, that
vacuum controller will close the valve it is controlling. If two
vacuum controllers are used, the pump will continue to work until
the second controller’s set point has been reached. Then the
second vacuum controller will close the valve it is controlling. The
pump switches off and the pump vent valve is opened.
If one of the two vacuum values falls below the hysteresis range,
the pump will switch back on.
Refer to the vacuum controller’s operating instructions for more
information.

Hazard of the pump head bursting due to excessive
pressure increase
WARNING
Î Do not exceed max. permissible operating
pressure (see chapter 5.1, page 10).
Î Monitor pressure during operation.
Î If the pressure exceeds the maximum
permissible operating pressure, immediately
shut down pump and eliminate fault (see chapter

Î Only throttle or regulate the air or gas quantity in
the suction line to prevent the maximum
permissible operating pressure from being
exceeded.
Î If the air or gas quantity in the pressure line is
throttled or regulated, make sure that the
maximum permissible operating pressure of the
pump is not exceeded.
Excessive pressure (with all of the related hazards) can be
prevented by placing a bypass line with a pressure-relief valve
between the pressure and suctions sides of the pump. For
further information, contact our technical adviser.
